Abstract

PROCESSO E INSTALAÇÃO PARA PRODUZIR ÓXIDO METÁLICO A PARTIR DE SAIS METÁLICOS. A presente invenção refere-se à produção de óxido metálico a partir de sais metalicos, o sal de metal, em particular, hidróxido de alumínio, é seco e preaquecido em um primeiro preaquecedor (2) a uma temperatura de 100 a 200°C, pré-calcinado em um segundo preaquecedor (5) a uma temperatura de 300 a 400°C e, então, calcinado em um reator (8) a uma temperatura de 850 a 11 OOºC para obter óxido metálico, em particular alumina. 1 O Após a pré-calcinação no segundo preaquecedor (5), um fluxo parcial do sal metálico é dividido e fornecido a um tanque de mistura (14), em que esse é misturado com o óxido metálico removido do reator (8).PROCESS AND INSTALLATION FOR PRODUCING METALLIC OXIDE FROM METALLIC SALTS. The present invention relates to the production of metal oxide from metal salts, the metal salt, in particular aluminum hydroxide, is dried and preheated in a first preheater (2) at a temperature of 100 to 200°C, precalcined in a second preheater (5) at a temperature of 300 to 400°C and then calcined in a reactor (8) at a temperature of 850 to 1100°C to obtain metal oxide, in particular alumina. 10 After pre-calcination in the second preheater (5), a partial stream of metal salt is divided and supplied to a mixing tank (14), where it is mixed with the metal oxide removed from the reactor (8).
